Section 5 (see- Figure 3) may be arranged with a rectangular portion removed from its lower left-hand corner, and may have holes 11 arranged for registering with holes 12 and 13 in carboard pieces Hand 15. Representations of separate registers do not appear on section 5. Three registers areshown on the cardboard piece let and four registers on the piece 15, and when these pieces are laced on section 5, one at'a time, the registers will be properly positioned with respect to the other elements of the bookkeeping-machine picture on the face of frame 1. r

A narrow slot 16 parallel to the adjacent bottom end of the machine picture and small rectangular holes or sight-openings 17, 18,

19 at the registers are cut inthe piece 14, and a like slot 20 and like sight-openings 21, 22, 23 and 24 are cut in the piece 15. Two narrow slots 25 and 26 are cut at the representation of a platen 80 parallel thereto. Two short narrow slots 27 and 28- are arranged to extend "upwardly from the upper slot 26 at right angles thireto, each positioned near an end of the slot 26. A cardboard slide 30 arranged for demonstrating a three-register bookkeeping machine has ruled columns 31, 32, 33, 34, 35, 36 and 37 with characters therein (except column representing entries on a ledger-shcehand it also has ruled columns 38, 39 and 10 with register figures therein. When the slide is assembled between layers 2 and 3, a guide for it is arranged by having the upper end of'the slide come out through the slot 25,

a and re enter through the slot 26. A'strap 41 between the slots may serve as a stop for the slide by engaging an offset portion 42 of the same, which extends downwardly toward the lower end of the frame 1 and comes out through the slot 16, which thereby serves as a lower guide for the slide 30. The characters in columns 31, 32, 33, 34;, 36 and 37 will appear over the strap 41 on the platen, and

the figures in columns 38, 39 and 4-0 will appear in the register openings 17, 18 and 19 in definite relation to said characters at the platen as the slide 30 is manipulated. In ike manner characters in columns 61, 62, 63, 64, 65, 66, 67 and 68 on slide 60 representing entries, and their associated register figures in columns 71, 7 2, 73 and 7 i may appear in the proper sight-openings of frame 1 when it is arranged to demonstrate a four-register bookkeeping machine.

A card 29bearing on its face a dummy heading of a ledger-sheet may be detaehably fastened in the slots 27 and 28 so that the ledger-sheet heading appears to be held one platen representation 80 and resting on a collatingtable 80. Several cards may be used with the frame 1. The ledger-sheet dummy appearing on a card 29 will preferably have columns and designations therefor arranged for a'certain slide or slides 30. A card 29 may also have a dummy work-sheet heading on each face.

To have the device in a com )act convenient form for. transportation, frame 1 may be folded without slide in it or as shown,

in Figure 7. In either case the bottom or right-hand layer 3 (see Figure 5) will preferably be swung over by means of the flexible strips 8 and 9 to overlie the normal upper layer 2 on which appears a photograph of the bookkeeping machine, thereby protect ing the photograph from injury by the lace 1 6 and other ob'ects. It will be noted thatthelayer 3 by ein flexibly connected to layer 2 with a space between them may have two functions. It normally serves as a bottom of frame 1, and also as a protecting cover for the machine photograph. To arrange the frame 1 in a small form to go in the salesmans brief-case or overcoat-pocket, the layers 2 and 3 are folded transversely. To obtain this end without detracting from the demonstration value of the machine photograph, the transverse dividing line between sections 4 and 5 is positioned where it does not touch any elements of the photograph on layer 2 made use of for demonstration purposes. A numeral-bearing'slide employedwithframe 1 will) not, as a rule, be used many times and may therefore be integrally folded wherever convenient. Since it is intended that the frame shall give long service, and since its neat artistic appearance considerably increases its demonstrating value, the means described abovefwhereby its good appearance may be preserved is of importance. 7 Y 'The machine represented on the frame 1. is similar to the Underwood standard hook" keeping machine. It has the platen representation. 80 and representations of the usual type-bars, keys and number-bearing register disks. A group of numeral-keys is shown at 81. Other keys and control-buttons are shown at 82, 83, 84 and 85. To begin a demonstration, the frame 1 may be placed flat on a desk, the slide. 30 being in its uppermost position, exposing at :the entry and register sight-openings sets of zeros or such numerals as may he desired for the particular demonstration. The frame 1 being held against movement by one hand, the slide is then slowly withdrawn by a pull on the offset portion 42 until the next succeeding sets of entry and. register numers .als are exposed at the sight-openings. Bl:

- is in its normal or uppermost position, thus.

exposing at each of the register sight-open ings 17, 18 and 19 a set of zeros and exposing at the entry sightppening the old balance see Figure 3. The first operation to be demonstrated ispicking up,i. e., causing to be shown in the middle register sight opening the previous debit balance S ki-1T2.

To do this, the slide ispul'led downwardly until 44.52 appears in the new balance column 37. At the same time, this amount, which is typed in column 8, is thrown into the middle re ister opening 18, and itis also shown again in the old balance coiu1nn36 for reasons explained hereinafter. The nextoperation is. toenter a debit oi: $12.56fior merchandise purchased March 3, posted in folio St, which is demonstrated by pulling the slide down another step, thus expose ing' 12.56iin the debitbolumn-Zldl This 'amount which-is typed in column 38, is

is also added to the amount (44.52) previously run into the middle register opening 18. The next operation to be demonstrated by moving the sli'deis the-typing of the balance 57.08), which amount is copied from the middle register. This amount, in the. actual machine,isirnnl-into the register represented by column 40' additively and into the-register represented by column 89 subtractivel'y, and will therefore clear the latter register thus proving thatthebalance was'correctly transcribed. As another check the star of proof may be typed after the balance (57.08); It will beunderstood that where a group of figures immediately follows, i. e., comes above,a like group in the same column of theentry section of slide-30,

' only the first set will affect the figures in the register columns 38, 39 and -10, as is indicated by the dotted lines n Figures Sand 9. Ccrtain groups of tiguresin both the entry col umns and the register columns are repeated to indicate that theywill remain in View on or above the platen printing line, or in the registers of the actual machine during two or more operations. a

Slides and are printed with-characters 101, 102, 10 3, 104 and 121, 122, 123, 124, respectively, some of which characters may be printed in different colorsfrom the others. These characterswill preterably be letters A and S representing abbreviations of addition and subtraction. They automaticallyrrappear in the round sighteopening shown at 8601* an actualdaookkeepingmachine and indicate tothe operatorthat the machine is set for an addition or subtraction operation, according to which letter appears. The color of the letter indicates whether the amount to be run into the re isters is acredit item or a debit item. Black ihdica'tesdebits and red mdica tes credits; .Each 1nd1'cator character has a reijerence line leading to one "oi the following explanatory pairs of. letters 5 BA, BS or RS, which represent ab:

breviations for black addition, lack subtraction and red'subtraction, respectively.- lt can be readily seen that these ind cator letters on the slides 100 and 120 appearingin the sight-opening 86 oft-he layer 2. as the slides are manipulated make it easier in demonstrating a bookkeeping machine to explain the computing operations taking place in the ing from entry numerals to register numer-' als on slides 100 and 120 areemployedto in-. dicate what registers are affected by runn ng a certain group of entry numerals into the machine; i

Demonstrations with slides 10 0 and 120 may be performed in like manner as described fer slide 30-andjthe slides shown in the application of Julian S. Hexter, Serial No. 25,218, filed April 23, 19:25, except that the functions of the indicatorcharacterswill need to be explained.

It can be readily seen that arranging frame 1 for use with a variablenumber of register sight-openings and tor use with n diiierent cards bearing different dummy headings of ledgersheets, permits the device to be used to demonstrate several accounts kept in" ledgers in different ways or forms.
